Be based on the method of citing systematic and comprehensive assessment, this paper attempts to establish the evaluating indictor system of agricultural websites and puts the 40 agricultural enterprises' websites into practical analysis. What's more, this paper applies the cluster analyzing software of SPSS into these samples. However, the information of websites and the level of function will play an indispensable role in the performance of websites' E-commerce.At present, appraisal study for websites is mainly conducted by third-party organizations such as Gomez and BirzRate and scholars from colleges and research institutes. These two groups adopt different appraisal methods and indices. Both domestic and international agencies adopt qualitative and quantitative measures to evaluate websites [1] , which might belong to different industries and have different purposes. Scholars including Zhang Xiaoshuan and Gao Ming (2007) [2] think currently there are nine kinds of measures for website appraisal: website tracking analysis, real-time software testing, network metrology, data analysis based on diary files, Business Value-Driven appraisal, comprehensive (systematic) appraisal, website appraisal based on information structure, eService Quality and website appraisal based on consumer behaviors.As for indices, most appraisal systems focus on two types: information and function, as it might be very difficult to acquire needed data in other ways. Seoyoung Hong and Jinwoo Kim(2004) [3] introduced architectural appraisal measures including firmitas, utilitas, venustas as first-tier appraisal indices. Their second-tier indices include internal reliability, external safety, content practicality, navigational usability, system interface appeal and interactive interface. Wang Weijun(2003) [4] , Zhu Weiwei and Chen Wenhui (2009) [5] think the following six indices should be adopted to appraise ecommerce websites: technology, interface, information, function, client service and operational performance. In terms of research methods, Zhang Hao and Meng Xiangrui (2009) [6] introduced dynamic fuzzy comprehensive evaluation Method to evaluate the dynamics and illegibility of indices on simulated conditions. Wang Yujia (2006) [7] introduced the fuzzy clustering analytical method from fuzzy maths, while Maaike J.van den Haak et al.(2009) [8] adopted the "think-aloud" method in psychology. Generally speaking, few people, either at home or abroad, can test their appraisal systems with practical examples. As for the research on industrial websites, José Joaquín Mira and Gilberto Llinás et al.(2006) [9] evaluated the quality of some public hospitals' websites, while E.M.Lewiecki and L.A.Rudolph(2006) [10] researched osteoporosis websites. On the domestic front, Cui Yonghua(2005) [11] appraised manufacturers' e-commerce websites, while Wang Yujia (2006) [7] and Qu Xiaojing (2005) [12] focused on agricultural websites.This paper deals with comprehensive appraisal systems for agricultural enterprises' e-commerce websites, taking into acco...
